My laptop wont charge!!! =(

I have an HP dv5. i've had it for 2 yrs and its been wonderful. basically, ive been stupid and kept my laptop plugged in constantly except for the occasional trip somewhere.

about a month ago it wouldnt charge. the light next to where the ac adaptor plugs in always lit up before telling me the computer registered that it was being charged. now my laptops completely dead because the light next to the ac plug in wont light up. i dont know if the problem is internal or if i need a new battery or adapter.

i'd like to go the cheapest route possible because i'm a college girl and am pretty much broke. lol. im sure you all know what thats like.

first- i tried plugging the charger in w/o the battery in the computer to see if it would at least charge the laptop. nothing happened. the blue light didn't turn on to say it registered a power supply.

second- yes the dc port and still has the pin in it. it doesn't look damaged but it does however wiggle around a lot actually.

third- i'm in college so i have practically no money to spend but i need this fixed asap. i think i'm going to get a new ac adapter anyway cuz mine looks a little retarded. but how should i go about fixing the internal dc port??

It takes a lot of training and know-how to sort DC sockets out.. it should only be done by a reputable source.
Did you buy extended warranty for the laptop? If not, you'd have to use google to find someone local..in the UK it can cost between £70 and £120 so whatever the equiv is wherever you are.

Sorry to break the news

If you are in college, perhaps you could approach the computer guys in there? They may be able to help, it would be cheaper that way as you can get the actual part for quite cheap.
